This pool volume calculator estimates the volume of a pool based on the shape of the pool. If the pool is rectangular and has two depths, you can calculate the volume as if it was two separate pools and add the results together.
- 1 cubic foot = 7.48 gallons
- pi = 3.14
The formulas are as follows:
Rectangle / Square Pool
Volume = Length x Width x Avg Depth x 7.48
Round Pool
Volume = pi x (Diameter / 2)2 x Avg Depth x 7.48
Oval Pool
Volume = Length x Width x Avg Depth x 5.9 (gallons – the industry average for oval pools)
